Tiphiinae are small to medium sized solitary wasps, up to 25 mm in length. The eyes are ovate and do not demonstrate emargination. The males have 10-13 antennal segments while the females have 10-12. The antennae may, or may not be, bent at a sharp angle. The thorax is normally coloured orange-red or black and the thorax of the wingless females has distinct dorsal segmentation. The pronotum is long and extends posteriorly towards the
tegulae. The spiracle cover lobes on the pronotum are lined with close fine hairs. There is no suture on the
mesopleuron. Wings are present in all males but females may be winged or wingless. If wings are present they are not folded longitudinally. Fore-wings have a distinct
pterostigma; and the wing venation is well developed. The legs show a fore femur which is not obviously thickened. ==Taxonomy==
